Making a Frost Walker-like Enchantment

[Siqhter]

I have recently been playing around with enchantments, and I setup the book/enchantment attributes in no time, but I'm having trouble mimicking the Frost Walker enchantment. For now, I am just trying to get it to act exactly like Frost Walker. Not sure if I'm registering wrong or just have overlooked something (I have never coded a functional enchantment). The enchantment book shows up fine, and applies to items in an anvil just as it should. No errors are logged, just nothing happens when I walk on ice. Thanks. 

 

UPDATE: I never called the freezeNearby class, so after adding to this to EnchantmentInit   

MyEnchantment.freezeNearby(livingBase, world, pos, 1);

it works. However it does it whenever a player steps on ice, not  when the enchanted boots are equipped.

        this.setName("myenchantment");
        this.setRegistryName(new ResourceLocation(Reference.MOD_ID + ":" + "myenchantment"));

        EnchantmentInit.ENCHANTMENTS.add(this);
    }

    @Override
    public int getMinEnchantability(int enchantmentLevel) {
        return 20 * enchantmentLevel;
    }

    @Override
    public int getMaxEnchantability(int enchantmentLevel) {
        return this.getMinEnchantability(enchantmentLevel) + 10;
    }

You never use this variable, I assume you want to. Plus there aren't any if statements in that block of code so of course it always happens.

Right, I figured that out and was just adding a conditional to check whether or not the player is wearing the boots. How can I check for a specific enchantment?

Well if the level is 0 there cant be an enchantment can there?

Got it! Thanks for your help in thinking about it logically.
